PHP 56 compatibility

[woqs]

Hi,

From version 2.1.0 you are telling on composer.json that your library is compatible with php 5.6 or above.

You're using the ?? in CassandraDataCollector though, making it 7.0 or above compliant.

Could you change this, by making a version compatible with 56 (like isset($a['a'])? $a['a'] : '';), and another one with the composer.json modified?

Thanks

thanks for the contribution

as PHP 5.6 is no more supported, I think I will update the requirement in the composer.json to php 7.2
